摘要
边部横裂是中厚板裂纹缺陷之一,其形成机理较为复杂。通过大量生产数据采集,把理论研究与当前热轧工艺特点、设备状况、操作模式等相结合,分析产生板材边部横裂纹的具体原因,并最终形成综合性的解决方案,取得了较好的效果。
Transverse edge crack is one of cracking defects on medium and heavy plate.By collecting a great number of production data,combining the theoretical research with current hot rolling process features,equipment conditions,operation modes,analyzing the specific causes of transverse edge crack,comprehensive solutions have been eventually established,and good results have been obtained.
